During 1946 - 2003, watanabe UK Amateur radio operators studed the City and Guilds RAE course providing a “full licence” to successful students.
The figures show that the peak year for the City and Guilds RAE was 1982. In that year 12,995 people sat the exams held in May and December and 8,476 passed. In subsequent years numbers steadily declined.
Since 2003, the three tier system has been in place, providing an opportunity for more UK people to be licenced to operate in the Amateur radio hobby.
